Effects of Coadsorbed Water on the Heterogeneous Photochemistry of Nitrates Adsorbed on TiO2
No full textNitric acid, a well-known sink of NOx gases in the atmosphere, has been found to be photoactive while adsorbed on tropospheric particles. When adsorbed onto semiconductive metal oxides, nitrate’s photochemical degradation can be interpreted as a photocatalytic process. Yet, the photolysis of nitrate ions on the surface of aerosols can also be initiated by changes in the symmetry of the ion upon adsorption. In this study, we use quantum chemistry to model the vibrational spectra of adsorbed nitrate on TiO2, a semiconductor component of atmospheric aerosols, and determine the kinetics of the heterogeneous photochemical degradation of nitrate under simulated solar light. Frequencies and geometry calculations suggest that the symmetry of chemisorbed nitrate ion depends strongly on coadsorbed water, with water changing the reactive surface of TiO2. Upon irradiation, surface nitrate undergoes photolysis to yield nitrogen-containing gaseous products including NO2, NO, HONO, and N2O, in proportions that depend on relative humidity (RH). In addition, the heterogeneous photochemistry rate constant decreases an order of magnitude, from (5.7 ± 0.1) × 10–4 s–1 on a dry surface to (7.1 ± 0.8) × 10–5 s–1 when nitrate is coadsorbed with water above monolayer coverage. Little is known about the roles of coadsorbed water on the heterogeneous photochemistry of nitrates on TiO2, along with its impact on the chemical balance of the atmosphere. This work discusses the roles of water in the photolysis of surface nitrates on TiO2 and the concomitant renoxification of the atmosphere

Get PDFEstimate the Impact of External Factors on College Decision Making Process for International Student. An Empirical Approach
Get PDFAs globalization grows stronger, more and more students choose to pursue their education dream in foreign countries. Meanwhile, the economic benefit that international students bring to host countries is undeniable. Thus, the demand for higher education continues to increase, consequently the competition among higher education institution become intense. With such a significant presence on the economic benefit, contributing by the international students in United State in the academic year 2016, It is time to examine the international students’ thinking process while they choose United States Universities as their four-year higher education location. Besides, it would provide an insight to admission officer, who worked closely with potential international candidate, to promote and attract international students in their preference. Therefore the administrator and college could point on those factor and improve their working goals. Based on this, I merged data by myself and estimate the impact of different factors on the decision-making process for international students in United States. My paper aims to analyze the key determinant of college decision making process for International students. Moreover, this paper attempt to weight the significance of each factor that affect international students’ decision
Luxury Tax and Competitive Balance in the NBA
Get PDFThe NBA is widely known as the least competitively balanced professional sports league in North America. Past literature has shown that as competitive balance declines, so does fan interest and revenues for both individual teams and the league as a whole. In 2003, the NBA implemented a luxury tax,a penalty mechanism that taxes teams who spend above the salary cap, in order to improve competitive balance. Using luxury tax and league level production data from the 1998 to 2016 NBA seasons, and a model that estimates competitive balance, this paper investigates whether the implementation of the luxury tax in 2003 positively affected competitive balance in the NBA. The results indicate that competitive balance significantly improved from 2003 to 2012 compared to the seasons prior to the implementation of the luxury tax. Additionally, I find that the more teams pay in luxury tax, the worse competitive balance becomes, suggesting that as teams stockpile more talent, the league becomes competitively imbalanced as a result
NFL Betting Market Efficiency: A Closer Look at the Final Day of Betting
Get PDFThis paper utilizes opening and closing betting lines on the day of play in the NFL to investigate if changes in the spread are a result of uninformed bettors. I formulate and empirically test the changes in the spread as they relate to home field advantage, favorites and hot hand betting. The results show that bettors tend to overvalue information and as a result, the actual scores shift less dramatically than the spreads on the final day of betting. A profitable betting strategy can be implemented betting against the shift in the spread. Additionally, it is more profitable to bet on home underdogs than away underdogs and more profitable to bet on away favorites than home favorites when betting against the shift in the spread

MDOCS Poster-2018-04-02, Palestinian Voices: Lyd in Exile
Get PDFApril 2, 6pm
Free and open to the public
Location: Somers Room
The Palestinian Voices series is organized and co-sponsored by the John B. Moore Documentary Studies Collaborative (MDOCS), the Environmental Studies and Sciences Program, International Affairs, Media and Film Studies, Art History, History, Hayat, and the Skidmore College Dean’s Office
Join us for a talk by Rami Younis and Sarah Friedland, and a screening of their work-in-progress documentary Lyd In Exile. Younis and Friedland have spent over three years researching and filming Lyd In Exile, and are in post-production. They will screen clips from their film and discuss their work collecting stories from the fractured community of Palestinians who were exiled from the city of Lyd (Lod in Hebrew), as well as the Palestinians who remain in this city.
Sarah Friedland is a New York-based filmmaker, media artist, educator, and the director of MDOCS Documentary Storytellers’ Institute at Skidmore. Friedland’s documentaries, made with partners Esy Casey and Ryan Joseph (Thing With No Name, Jeepney, and The Rink), have screened widely in the U.S. and abroad and have aired on PBS. Their films have been supported by grants from the Jerome Foundation, the Paul Newman Foundation, the Ford Foundation JustFilms Program, and the Center for Asian American Media. In 2009, after the debut of her feature documentary Thing With No Name, she was named one of the “Top 10 Independent Filmmakers to Watch” by The Independent. She has received residencies and fellowships from the Center of Contemporary Art in Pont-Aven, France; the LABA House of Study; the Palestine American Research Center; the MacDowell Colony; and Meerkat Media.
Rami Younis is a Palestinian writer and activist from Lyd, who graduated from Hebrew University in Jerusalem. He writes for the online magazine +972, and serves as a writer and editor at the Hebrew sister site Local Call. He is one of the founders of the Palestinian activist group Khotweh, which was active on the issues of home demolitions and Palestinian identity in Lyd and Ramleh, mixed Jewish-Arab cities in occupied historical Palestine. Rami served as a parliamentary consultant and spokesperson for Palestinian member of Knesset Haneen Zoabi. Rami is also co-founder and manager of the first Palestine Music Expo, an event that connects the local Palestinian music scene to the worldwide industry.
This talk and screening are part of exhibition This Place, on view February 3 through April 22, 2018, as well as the Palestinian Voices series.

Examining Political, Environmental and Economic Determinants of Refugee Flows from Mainland China to North and South Countries
Get PDFThis research examines refugee migration originating from Mainland China to North and South countries, like Australia, United States, United Kingdom, Nepal and India. To analyze refugee flow, I used four different determinants: political, civil, environmental, and economic to isolate the importance of each determinate. The analysis was derived from the gravity model to estimate the flow of refugees. I estimated the random effects model for all three of my models. The empirical analysis demonstrated that PTS and fertility in China were the most significant determinant within developed countries for refugee flow, whereas the most important determinants for developing countries were fertility rate, distance, and population. I also find that in the overall model, all variables except China’s GDP per capita were significant determinates of refugee flow. The analysis concludes that refugee flow to North countries is due to political and economic indicators while refugee flow to South countries is a result of distance and cultural components
